. To all whom it may concern:

Be it known that I, OrIARLs J. JOHNSON, a'citlzen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and use ful Improvements in Fastening Devices for Doors and the Like, of which the following is a specification.

This invention relates to improvements in means for fastening the doors of ice-boxes, china closets, cabinets, and the like, and it consists in certain peculiarities of the construction, novel arrangement and operation of the various parts thereof, as will be hereinafter more fully set forth and specifically claimed.

The principal object of the invention is to provide a fastening device of the abovenamed general character, which shall be simple and inexpensive in construction, strong, durable and effective in operation and so made that each door will be fastened thereby at two or more places and in such a manner that it will be firmly held in its secured position thereby preventing rattling or warping of the doors.

Another object of the invention is to provide means for fastening both of the doors at the several points at the same time, and by the use of a single knob or lever, and when desired to lock the parts in their secured positions by means of the bolt of an ordinary lock.

Other objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enable others skilled in the art to which my invention pertains, to make and use the same, I will now proceed to describe it, referring to the accompanying drawings, in which Figure 1, is a face view of a portion of a piece of furniture such as a cabinet or bookcase or an ice-box, which as is well known, are usually provided with a door-way having two doors hinged to close the same; Fig. 2, is an enlarged vertical sectional view of the upper portion of the door-frame and a part of one of the doors showing said parts equipped with fastening means to draw and securely hold the door in its closed position; Fig. 3, is an enlarged view partly in section and partly in elevation of the lower portion of one of the locking bars of one of the doors, showing the roller-bearing-foot thereon; Fig. 1, is an enlarged perspective view of the lock casing showing it detached; Fig. 5, is a plan sectional view thereof taken on line 55 of Fig. 4, looking in the direction indicated by the arrows; Fig. 6, is an inner face view of a portion of the cabinet or piece of furniture showing my improved fastening mechanism thereon with the parts in the positions they will occupy when the doors are fastened. Fig. 7, is a vertical sectional view taken on line 77 of Fig. 6, looking in the direction indicated by the arrows; Fig. 8, is a vertical sectional. view through a portion of one of the auxiliary fasteners showing the bolt therefor in its unfastened position; and Fig. 9, is a sectional view taken on line 9-9 of Fig. 1, looking in the direction indicated by the arrow.

Like numerals of reference, refer to corresponding parts throughout the different views of the drawings.

The reference numeral 10, designates a piece of furniture as a whole which is provided with a door-way 11, to the side walls or jambs of which are hinged doors 12, which meet at their inner edges when closed as is clearly shown in Figs. 1, and 6, of the drawings. Located ina suitable mortise at the bottom of the door-way 11, and at the middle thereof, is a lock casing 13, which look may be of the ordinary or any preferred construction, and may have a bolt 14:, in its upper portion to be projected and retracted by means of a key 15. Journaled in the lower portion of the casing 13, is a shaft 16, which has on its outer end a handle or lever 17, by means of which the fastening or locking bars of the doors are raised. The outer portion of the shaft 16, is encircled by a sleeve 18, which is secured at its inner end to the casing 13, and within said sleeve is located a spring 19, which is coiled around the shaft 16, and has one of its ends secured to said shaft and its other end to the sleeve for the purpose of normally holding the shaft 16, in such position that it will not project the bolt which it operates.

Mounted on the inner end of the shaft 16, is an eccentric 20, which is provided with a pin 21, to which one end of a link 22, pivotally connected the other end of which link is provided with a slot 23, for the reception and operation of a pin 24:, secured to a bolt 25, which is slidably mounted between two guide pieces 26, on the inner surface of the casing 13, and at the upper por- .tion thereof. Located at the middle of the upper portion of the door-way 11, is a boxlike casing 27, which is fitted in a suitable mortise in the front of the piece of furniture and has its lower end flush with the upper edge of the door-way 11, and open. This casing is provided with a vertical partition 28, having its inner surface upwardly and inwardly inclined as is clearly shown in Figs. 2, and 7, of the drawings, thus forming a compartment on each side of said partition (see Fig. 6,) in which are journaled rollers 29, the peripheries of which project slightly beyond the inner edge of said partition. Eachof the doors 12, is provided at its inner edge with a vertical groove 30, open at its top and bottom in each of which is located a bar 31, the upper end of each of which is upwardly and inwardly beveled as at 32, (see Figs. 2, and 7,) of the drawings. The lower end of each of the bars 31, is provided with a horizontally disposed foot 33, on which are journaled rollers 34, to contact with the lower surface of the door-way 11, or bolts 14, and 25, when the doors are closed. Located in a suitable mortise at the lower inner corner of each of the doors 12, is a casing 35, through the inner portion of each of which the bars 31, are vertically extended and each has connected thereto at one of its ends a link 36, which is fulcrumed 011 the casing 35, and each link has pivotally secured to its other end one end of a bolt 37 which is extended through the lower portion 35, of its casing and is adapted to impinge at its lower end against a member 38, having its inner surface downwardly and inwardly inclined, see Fig. 8. Each of the members 38, is preferably seated in a mortise 39, produced in the lower end of the door-way and each of said members is preferably provided with a roller 40, to contact with the lower end of the bolt 37, which is beveled as shown. The inner end of each of the links 36, as well as each of the bars 31, is normally held in its lowered position by means of a spring 41, which is secured at one of its ends to the casing 35, and rests at its other end against the inner portion of the link.

As is shown in Fig. 9, the lower inner corner of each of the casings 35, is cut-away to permit of the operation of the foot 33, on each of the bars 31, and also for the reception and operation of the locking bolt 14, which when projected, will be interposed between the bolt 25, on the inner surface of the casing 13, and the front lower portions of the casings 35, thus assisting the bolt 25, to hold the bars 31, in their raised positions, and also looking the parts at the lower ends of the doors. While I have shown a casing 27, at the upper portion of the doorway equipped with rollers 29, and have also illustrated the feet 33, on the bars 31, as having rollers 34, thereon, and have also shown the members 38, with rollers 40, thereon, and while I prefer to employ the same in heavy structures, such as ice-boxes, yet I do not desire to be limited to their use, as they may be dispensed with, but it is apparent that by using the same, the beveled upper ends of the bars 31, and the beveled lower ends of the bolts 37, will be forced inwardly, thereby, thus causing the doors to be securely held in their fastened positions and it is also obvious that the rollers 34, on the feet 33, on the lower ends of the bars 31, will roll over the lower edge of the door-way as well as the bolts 14, and 25, when they are retracted thus assisting the doors in closing. IVhen these rollers are omitted, it is apparent that the beveled members 28, and 38, coacting with the beveled ends 32, of the bars 31, and the beveled ends of the bolts 37 will also act to draw the bars inwardly, when said bolts are projected, thus securely holding the doors in their fastened positions.

From the foregoing and by reference to the drawings, it will be readily understood and clearly seen that when the handle 17 on the shaft 16, occupies the position shown at 17 in Fig. 6, in which position it will be normally held by means of a spring 19, on said shaft, the bolt 25, which I will call the master bolt, will occupy its lowered position as shown by dotted lines in said figure, and the bars 31, will be lowered out of engagement with the sockets in the upper portion of the door-way. At the same time, the bolts 37, by reason of the springs 41, acting on the links 36, will be raised out of engagement with the sockets 39, and members 38, thus permitting the doors to be opened. When it is desired to fasten the doors, the same may be closed and the handle 17, turned up to the dotted position shown at 17, in Fig. 6, in which operation it is apparent that the bars 31, will be raised by the master bolt 25, in which operation the bolts 37, will be projected downwardly. I11 the above-named movements of the parts, it is apparent that the beveled ends of the bars 31, and the similarly shaped ends of the bolts 37, will impinge against the inclined parts 28, and 38, respectively, and against the rollers which said parts carry when the same are used, thus drawing the doors inwardly and securely holding them in position where they may be locked by means of the key-operated bolt 14, which bolt in some instances, where the parts are of light construction, may be used for operating the bars 31, instead of the master bolt.

Having thus fully described my invention what I claim as new and desire to secure by Letters-Patent is 1. In a fastening device, the combination with a door-frame, of a door hinged to close the same, a longitudinally movable bar on the door, engaging means on the frame for one end of said bar, a master bolt movably mounted on the frame to contact with the other end of said bar to raise it to its operative position, and means to operate the master bolt consisting of a handled shaft rotatably mounted below the master bolt and an eccentric mounted on the shaft to engage the lower end of said bolt.
